The lace wigs with different hair knotting techniques are used to knot hair into the base, providing different performance and results. The quality of the workmanship will have a great impact on the finished look.
The lace wigs with single hair single knots are considered the best method of knotting producing a tiny knot for each individual hand-tied hair. Two or three individual hairs can be single knotted into the base of lace wigs at one time speeding up the process to the detrimental of creating a larger knot with less aesthetically pleasing finish.
The lace wigs with double knots literally include knotting hair twice to produce a double knot which provides a stronger, more robust knot for the hair knotted into the base of lace wigs. The resultant knots are however even more visible under close inspection. This is a particular problem when trying to create a natural hairline and for this reason most front hair lines should be single hair single knotted on a flesh tone lace material.
Single Knots are hard to detect, but easy to shed, by contrast, Double Knots are hard to shed, but easy to detect. As to the advantages and the disadvantages of the two kinds of knots, we recommend single knots in front hairline 2 inches or around perimeter 2 inches for the lace wigs.
